' Myinv'ention relates toimprovements .in

water heating apparatus.

- 'It' is partieularlyadapted for providing steamfor washing'outlarge cream cans at "5 country cream stations.- 4

I Oneotthe objects, of my inventionis to 1 provide anapparatus with which steam can be quickly made to be used to remove the thick cream which adheresito' the walls of A further object of my invention is to provide :an apparatus 'of the kind described, which is simple, relatively cheap to "make, which is durable, not liable to get out oforder, 1 sanitary,and with which hot water and steammay be'very quickly'produced.

Still another object of my inventionisthe provision of a novel and eflicient steam boiler,

and novel means by which the steam pro- 7 duced therein may be utilized for preheating a relatively largea-mount of water, or'for steaming cans to effect the dissolving of heavy cream on the inner walls thereof.

The novel features of my invention are 5 hereinafter fully described and "claimed; 1

' Y in-the'casfing 'lgprovides at one of itssides a icompartmentaohaving an opentop and Fig. 1 is a side elevation partly broken 0 away of my improved can cleaningappara adapted tohold water for washing cans. At

the other "side of the partition 4, and extending horizontally therefrom'to an adjacent end wall of the casing, is a partition 6, which forms in the casing an upper compartment 5 7, comprising a tank adapted to hold water, and a lower compartment 8 adapted to re- A ceivec' gaseous products of combustion for heating the taiik'fiand which has an outlet communicating-with a pipe 9 forcarrying eo off the fumesand burnt gas, and whichmay contain the usual dampeninot'shown; a

Below the casing'l, and underneaththe compartment 8 is'a steamboiler, comprising an outersh'ell 10 through which vertically extends an upwardly tapering flue 11,'the upper end of which" is attachedto the bottom of the casing 1 and which'discharges intothe compartment 8. l f 1 Inthe shell 10 is a transverse horizontal partition 12 through which the flue 11 extends, a

and which divides the shell into an upper 'chamber 13 and a lower chamber 14. These two compartments may be respectively provided. near their'lower ends with drain-cocks 15 and16, the latter being attached to a water V conductor 17,having its upper end connected to the partition 6 and communicating with the tank compartment? The lower end of the conductor connects to the shell 10 andvso p v In the side of the casing land COIIIIIlllQiA eating with the compartment 7 near thebottom o f'the latter is a drain: cook 20. 'i V One sideof the casing 1, also provided with a drain cock 21, whi'chycommunicates with the compartment 5 near the bottom of 1 Connectedto and 'ext d through the,

partition 12 are two vertical pipes 22,,the

upper. ends of which connect-witha'iidd-is charge into a ringpipe 23, at opposite sides respectively of theflueyll In theupper side to r six

of the ring pipe 23, which encircles the fine 11, are provided holes 24.

A steam conductor 25 having in it a safety valve 26, is connected to the top of the shell and communicates with the compartment 13. Said steam conductor has two branches 26 and 27 in which are respectively located two controlling valves 28 and 29, having respectively swinging arms 30 and 31, to which are pivoted a horizontal operating member comprising a horizontal bar 32. The valves 28 and 29 are respectively provided with. transverse ports 83 and 34 disposed at right angles to each other, so that when the bar is reciprocated, the valves will be alternately opened and closed. 5

When the valve 28 is open, thevalve 29 will be closed, andviceversa.

The branch 27 extends through the bottit-1110f the'casing land through the bottom or thetank compartment 7,: and has in said compartment a return bend, whereby the branch will .dischar e steam'downwardl ad a funnel shaped receptacle 38, the upper large end of which is fastened to the underside of a horizontal apron 40, which is a projecting part of the top 2, and which has a vertical hole 41,,through which may be'insertedthe mouth and neck 42 of alarge cream can 43, such as is used to hold milk or cream. By having the walls otthe receptacle 38 down wardly converging it is adapted tosupport in inverted posit-ions cream cans having mouths of different diameters.

The discharge end of the branch 26 extends upwardly so as to discharge directly into the mouthot' a cream can supported on the re ceptacle 38; The latter atits lower end has an outletwhich discharges into an elbow spout a l, which is swiveled to swing in a hori t-iontal plane, so as to discharge into either of two receiving cans, not shown, but which may he placed side by side under thespout.

Below anddischarging into thefiue'll is a gas or oil burner 45, having a pipe 46 connected toa supply tank, not shown, A drip can 47 may be provided under the burner 45. In the operation of the invention, the

burner is lighted, and theval-ve 19 is f opened, thus permlttingwater to pass from 1 the compartment Tthroughthe waterconductor 17 into" the compartment 14. The flame from the burner will heat-the flue l1 and the products of combustion passing into the compartment 8 and out the pipe 9 will heat the Water in the boiler and in the tank compartment 7. The bar 32 is moved to close the valve 28 and open the valve 29, thus permitting stein, when formed to pass with water into the compartment 13 through the pipes 22 and ring pipe 23. The steam will pass into the pipe 25, and thence into and through the branch 29, and will be discharged into the tank compartment 7, thereby heating the water in the latter to near the boiling point. The water discharged with the steam from the ring pipe holes 24 will be further heated by striking. the fine 11 in the chamber 13. y 7

Then the water in chamber 13' has been convertedto steam,.the barj32 is moved to the position shown in Figs. '3 and 5, thereby closing valve 29and opening valve 28, thus 1t ermitting steam to pass through the branch- 26 into the can supporting receptacle 38. It now a cream can, which has been emptied is inverted and placedwith the month end resting on. the converging walls of the receptacle 38, the steam will be discharged fromthe branch '26 directlyiinto the can 43 through the mouth thereof. thus dissolving the thick cream which has stuck to the insides of'the can. The small amount ofwater which has been condensed from the steam, mixed with the dissolved cream, will flow out of the can 4-3 into the receptacle 88, and through the spout L4 into a container, not shown, set to catch the dissolved cream. When most of the cream is thus removed from the can, the latter may be -removed and washed in the compartment 5. The spout Mmay be swung so asnot to discharge water from the branch 26 into the container which holds the dis solved cream. Another cream can may now be placed inverted in the receptacle, the spout restored to its original position, and the operation then repeated.

As long as the tank 7 holds, water, the operation may be kept up, .and freshwater may be added to the tank 7 from time to time, the bar 82 being moved to a position 'in which the valve 29, will beopen and the valve 28 closed, when it isirequired to heat the water 7 in the tank 7, providing the heat from the flue ll'is insufi icient to retain thefwater in the tank su'fiicientlv heated-to .efilect quick conversion into steam of the 'water in the boiler, as'inav-occnr incold weather.

I do not limit my invention to the structure shown and described, such modifications,

as fall within the scope of theappended claims, may be made without departing from the spirit of my invention. h
